Rev. 1.2.2
appropriate bit combination the user can configure the IC to function as a master or a slave when
two or more XRP7708s are used to convert power in a system. Automatic clock selection is also
provided to allow operation even if the external clock fails by switching the IC back to an internal
clock.
External Clock Synchronization
Even when configured to use an external clock, the chip initially powers up with its internal clock.
The user can set the percent target that the frequency detector will use when comparing the
internal clock with the clock frequency input on the GPIO pin. If the external clock frequency is
detected to be within the window specified by the user, then a switchover will occur to the external
clock. If the IC does not find a clock in the specified frequency target range then the external clock
will not be used and the IC will run on the internal clock that was specified by the user. If the
external clock fails the user can chose to have the internal clock take over, using the automatic
switch back mode in the SET_SYNC_MODE_CONFIG register.

Synchronized Operation as a Master and Slave Unit
Two XRP7708s can be synchronized together. This Master-Slave configuration is described below.
"    Master
When the XRP7708 powers up as a master unit after the internal configuration memory is loaded
the unit will send CLK_OUT and SYNC_OUT signals to the slave on the preconfigured GPIO pins.
"    Slave
When powering in sync mode the slave unit will initially power up with its internal clock to transfer
the configuration memory. Once this transfer occurs, then the unit is set to function as a slave unit.
In turn the unit will take the external clock provided by the master to run as its main internal clock.
